This invention relates to irrigating appacharge orificev in a manner so that an ideal rat'us and particularly to that type whichis spray results. The spray in thiscase is not installed in lawns. j what might be termed a mechanical spray,

In us'e, thesesystems usually include a net but is one which results from the speed of v6 work of piping sunkin the lawn with risers rotation of the water entering therevolving arranged at suitable points to supply sprinchamber. A spray produced in this way is kler heads which are at grade and which prouniform throughout .in the sense that the duce overlapping spraysintended to waterthe W ter is distri uted evenly'over the entire entire area.

its apex in a spray orifice 9 of suitable diameter to produce the proper spray. The structure thus far described is provided with a threaded hub or shank 10 adapted to be screwed into asuitable coupling 6. Forming a part of this hub or shank 10 is a tubular extension or hollow body 11 threaded internally at 12 and provided with opposed tan gential, vertically disposed slots 13, these slots beingrdirected inward at a tangent in the direction of the threads 12 0f the extension 11 so that the water passing in, and revolving in the extension as will appear,'will be in the same direction as the threads. The

. slots 13 open out at the bottom of the extension 11 andterminate, above, at substantially the base of the shank 10. The opening in the tubular extension 11 extends up into the hub with a, curved upper outer corner at 142, this opening being larger than the spray orifice 9, as shown. Engaging the thread 12 of the extension 11 is a revolving chamber adjust-- ing plug 15 having an upwardly tapering top at 16 provided with a polygonal recess 17 adapted for the insertion of a suitably shaped wrench which may be projected through the spray orifice 9. By ad usting tudinally along the skirt, said skirt being internally threaded and enclosing an inner the skirt member extend in the same direc-- tionas the upward spiral of the threads in said chamber, whereby the whirling effect upon the water produced by the slots is as Vsisted by the upward travel of the water in the threads of said chamber. 7

By anadjustment of ,1 Vteristic, but may be reduced in size and area covered without sacrifice of efficiency. It has also been found that with a revol ving chan 1 ber, supplied in this way with water from tangential slots, the speed of the revolving volume'of water 111 the revolving chamber this .plug the operator at once reduces the causes the water to pass up around the lip of the spray orifice 9 and to adjust itself in the conical recess 8 and project outward in a somewhat conical stream with uniformdensity whereby a uniform spray results.

The plate 7 may be provided with opposed openings 18 for the reception of a wrench for removal of the spray head. lVhen the installation is made so that the risers come substantially to grade and th-ehead is removable, 1t is possible, after installation, to replace a head without disturbing the lawn and without any. grade difficulty.
